Mathematical model of controlled motion of a wing-in-ground craft near the shield surface along a given plane trajectory

Abstract

The paper considers the development of a methodology for calculating the motion parameters of wing-in-ground (WIG) craft along a given arbitrary trajectory in the horizontal plane and the possibility of performing this motion. The initial data include a given trajectory of the motion, a set of aerodynamic characteristics of the WIG Craft, including the characteristics of controllability, restrictions on motion parameters and available control actions. The calculation method is based on solving a system of differential equations of spatial motion of the aircraft. The motion along a given trajectory is provided by a virtual automatic system based on PID controllers. The motion is evaluated as possible if the imposed restrictions are not violated in the process of constructing parametric functions of control factors and motion parameters. The technique involves the use of various strategies for controlling the WIG Craft near the shield surface. The developed mathematical model makes it possible to conduct research within the framework of the design tasks of various layouts of WIG Crafts.
